The cash was found in august inside two cars in Escondido. It's the largest cash seizure ever made by the Border Patrol in San Diego County.

Authorities say they followed a speeding Kia Forte from a freeway and pulled it over. They found nearly $34,000 in vacuum-sealed bundles in the center console.

A second car, a Volkswagen Passat, raced away but was later found abandoned in a cul-de-sac and the driver was found hiding in some brush. Authorities say they found more than $3 million in cardboard boxes in the trunk.

The two drivers pleaded not guilty Wednesday to federal currency-smuggling charges.

This story has been corrected to show that the seizure was in August, not Tuesday.
